And then all those trees dry out because waterbed can't carry this many, and they catch fire. See California, nearly every year. It's a 100% natural process for them to dry out and catch fire from time to time. It's just not very conducive to permanent carbon capture. The proposed solution (irrigation) is the most pie-in-the-sky part of the plan. It's "solar energy, ???, profit" basically.

I like the scalability aspects of this. I don't think we have a technical solution that is as scalable as a biological one. I do think that simply "planting trees" is not going to do the trick though.
